Sayyiduna Abu Hurairah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Do not go out to meet those bringing grain into the city from outside, and whoever goes and meets such a caravan and buys something from them, then the seller (owner) has the choice, after reaching the market, (whether to keep the transaction or cancel it)."
